Abstract

The invention discloses a cedarwood fiber-based bio-composite material and a preparation method thereof. According to the preparation method, the advantages of good toughness, corrosion resistance, moth resistance, low cost and the like of abandoned cedarwood fibers are fully utilized, the cedarwood fibers are processed through a high temperature extrusion process in an earlier stage, then the cedarwood fibers are mixed with polyvinyl chloride (PVC), and matched with other additives, and proper processing steps and parameters are adopted, so as to obtain the bio-composite material which is high in strength, high in toughness and low in cost by squeezing granulation through a screw rod. The material can be processed to form various products through ways of injection molding, extrusion, mould pressing, machining and the like, is widely used in the fields of packaging, electronics, communication, furniture, decoration, automobiles, airplanes, war industry and the like, is capable of replacing the materials of plastic, logs and the like, and has very good social benefit and economic benefit.

Description

technical field [0001] The invention relates to a Chinese fir fiber-based biomass composite material and a preparation method thereof, belonging to the field of new materials and their molding processing, and the invented product can be used to replace plastics, wood and the like. Background technique [0002] At present, the materials used in the fields of packaging, electronic appliances, home decoration, automobiles, aircrafts, and military industries are mainly petroleum-based plastics, and some logs are used. However, plastics have the disadvantages of being non-biodegradable and polluting the environment. At the same time, the oil resources are limited and not sustainable. The use of a large number of logs will cut down a large number of forests and destroy the ecological environment. Therefore, the combination of plant fibers and some polymer plastics produces a higher-performance wood-plastic composite material, which can replace wood and plastics and alleviate reso...
